BLAG comes with gnomemeeting, which is a netmeeting compatible video conferncing program.
If gnomemeeting wasn't installed when you did your initial install, you can download and and install it like this (run as root from command line):
apt-get update
apt-get install gnomemeeting
It will then be in the "Internet" menu item as "Video Conferencing"
You can also update your BLAG system by running:
apt-get update
apt-get dist-upgrade
This will sync you with the current release, 9002.
(BLAG uses both RPM and apt by the way)
